Pretty sure we need this existing logic to parse output from the tools? [native-packager etc].
From what i remember, it gives us output in that format (error: warn: info: etc) that we need to parse and packagerize.
Also wonder if we can have some sort of pass-though logic for packager output ([ERROR], [WARN],[INFO],[BUILD]), so we don't substring them only to prefix the same headings ([ERROR], [WARN],[INFO],[BUILD]).
